Answer:
2.51x10⁻⁵ mmol MgF2/L
Explanation:
To find the concentration in mmol / L we need to convert μmol to mmol (1000μmol / 1mmol) and mL to Liters (1000mL / 1L) as follows:
μmol MgF2:
0.0113μmol MgF2 * (1mmol / 1000μmol) = 1.13x10⁻⁵ mmol MgF2
Liters solution:
450mL * (1L / 1000mL) = 0.450L
Concentration in mmol/L:
1.13x10⁻⁵ mmol MgF2 / 0.450L =
<h3>2.51x10⁻⁵ mmol MgF2/L</h3>
Answer:
The common name for 2-butanone, a readily available solvent, is B-butanone
<h2>Answer:</h2>
D) The geosphere, hydrosphere, and atmosphere
<h2>Explanation:</h2>
During the carbon cycle, various processes move carbon from the geosphere to the atmosphere such as volcanic eruptions release carbon dioxide from molten rock beneath the earth's surface to the atmosphere. Carbon can leave the soil through soil respiration which releases CO2, or by erosion which can carry it into rivers or the ocean, where it then enters the hydrosphere. Carbon is found in the hydrosphere dissolved in ocean water and lakes and hence the cycle continues.
Answer:
When dry ice is exposed to warm air, a gas called carbon dioxide is produced through a process called sublimation
